Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 www.labthink.com Testing Water Vapor Transmission Rate of Medical Hydrogel Dressings Medical hydrogel dressings have become increasingly popular due to their excellent biocompatibility and wound healing properties. One crucial aspect of their performance is water vapor transmission rate (WVTR), which measures the rate at which water vapor can pass through the dressing. A well-balanced WVTR is essential for optimal wound healing. If the WVTR is too low, moisture can accumulate under the dressing, leading to maceration and delayed healing. Conversely, if the WVTR is too high, the wound may dry out, hindering the healing process. To accurately assess the WVTR of medical hydrogel dressings, the Labthink C360M water vapor transmission rate test system is a reliable and efficient tool.

Fill the 6 test cups with distilled water and clamp the specimens onto a permeable cup. 3. The cups are then carefully placed in the C360M test chamber. 4. set on the instrument's control panel the Test condition that mimics the real-world usage scenarios, 37°C and 80%RH. 5. Once the parameters are set, press start on the touch screen to initiate the test, and the instrument automatically monitors the weight change of the cup over a specific period. 6. The collected data...
